Operation Manual for Single Chamber ICE Bladder


Handcarry Tethered ICE Water Circulation Cooling System combines a tubing-lined vest with a liquid cooling system housed in a handcarry pack to form a tethered thermal regulation device. The vest is a highly engineered stretchable garment that weighs a mere 0.5KG (1.1 lbs.), dry weight. Front zipper design which is easy to don and comfortable to wear against the body. Stretchable fabric provides a snug fit for max thermal transfer. The liquid cooling system is a separate ice pack that weighs 1.5KG (3.3 lbs.), dry weight.  It contains a 3.0-liter detachable bladder, circulation pump, and power switch.  When operating, it’s audible output is 45dBA.  Cooling energy is provided by freezing the water in the ice bladder.  Power is derived from the 7.4V rechargeable battery. To operate the system, connect the vest tubing to the handcarry pack using the quick-connect fittings.  With the pump unit attached to the battery power, using the remote control, press "Up/Down" buttons to set the desired water flow level, level 1 is 250ml/min, level 2 is 350ml/min, level 3 is 450ml/min. Setting is completed when LED number stops blinking. The steady number shows the current liquid temperature. Press switch "on", the pump circulates cold water in a continuous loop between bladder and garment. Indicator "dash" shows the On/Off status of pump. Depending on ambient temperatures and workload, flow control pump regulates the circulation temperature as need. Slow water flow may save the cooling energy and extend the cooling time. Users can expect a cooling duration anywhere from 2 to 4 hours depending on flow rate, ambient temperatures and workload. Additional bladder and battery can be purchased for prolonged cooling.  Ice cubes can also be used for prolonged cooling, although the cooling time will be lessened.
